Django 3.1: models.py: missing 1 required positional argument: 'on_delete'

Hi

Seems like there is on_delete field missing in twython_django_oauth/models.py:

  File "/home/brezerk/develop/example/.venv/lib/python3.6/site-packages/twython_django_oauth/models.py", line 5, in <module>
    class TwitterProfile(models.Model):
  File "/home/brezerk/develop/example/.venv/lib/python3.6/site-packages/twython_django_oauth/models.py", line 11, in TwitterProfile
    user = models.OneToOneField(User)
TypeError: __init__() missing 1 required positional argument: 'on_delete'
